    <p><strong>Preface</strong></p> <p>I'm writing an web-server that gives to users an access to some program written on C (I'm using an Python wrapper over this C-program, it is <a href="https://sourceforge.net/projects/pyclips/" rel="nofollow">PyCLIPS</a>). To serve a lot of users, the web-server has to start a lot of copies of this C-program, because one copy can serve very few users in the same time, about 1-3 users. In addition, each user should work only with his own copy, therefore should be a lot of copies of the C-program. </p> <p><em>This C-program is a <a href="http://clipsrules.sourceforge.net/" rel="nofollow">CLIPS engine</a> if it'll help to understand.</em></p> <hr> <p>So, to solve this design problem, I want write a Twisted TCP server that will be like a pool of long-running-processes. Each of long-running-processes is a small Twisted TCP server that gives an access to one copy of the C-program. </p> <p>In example, a user ask the pool-server to reserve a long-running-process for him, then the pool-server create and run a long-running-process that starts listening on some port, then the pool-server return the host and port of this long-running-process to user. Now, user can communicate with this long-running-process directly. </p> <hr> <p><strong>Questions</strong></p> <ol> <li>How start these long-running-process from the pool-server? The pool-server and each of long-running-processes are should be separate Twisted servers.</li> <li>Is Twisted a good choice for these aims?</li> <li>Maybe there are another ways how solve this design problem?</li> </ol> <p>Thanks a lot.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
